IMPROVEMENT IN STEAM BOILING APPARATUS.

Specification forming part of Letters Patent No. 135,142, dated January21, 1873.

To all whom it may concern:

Be it known that I, ELIE MoNEUsn, of the city and State of New York,have invented an Improvement in Steam Boiling Apparatus, of which thefollowing is a specification:

Apparatus for heating water, boiling, or cooking have been made in whichthe steam has been introduced in a coil or range of pipes within theliquid. This is objectionable, because the boiler cannot easily becleaned, and any substance between the pipes cannot be removed withfacility. To avoid this difficulty a steam-jacket has to be employed.This is subject to three serious objections: First, the steam-heat iswasted by radiation from the jacket; hence, there is loss both of heatand time during which the contents are becoming heated. Second, theparts have to be very strong in order to withstand the pressure ofsteam. This necessitates increased weight inthe vessel and correspondingexpense, and the heat is not as rapid in its action through the greaterthickness. Third, in cases of culinary'vessels it is usual to line themwith a sheet of block-tin, and this is seldom attached to the coppervessel, except at the upper edge; therefore, if there is any moisturebetween the two thicknesses the vapor generated by the external heatproduces a separation and a non-conducting space, and in this mannerexpensive vessels are often rendered useless.

My invention is made for obtaining the entire heating power of thesteam, for dispensing with coils, for giving facility for cleaning, forlessening expense of construction and weight of material, and foravoiding risk of injury to the containing-vessel.

My invention consists in a steam-dome introduced within thecontaining-vessel near the bottom thereof, and connected with steam andwaste-water pipe to a boiler or other steamgenerator, so that thecontents of the boiler- V such as water, soup, beer, or other liquidshall be heated with rapidity by the direct ac tion of the steam in suchdome; and the ves sel is free to be cleaned and its contents entirelyremoved. This steam-dome is available with copper, iron, and woodenvessels, whether coated or not with tin enamel, sheet lead or tin, orother material; and the pressure of steam that can be employed is onlylimited by the strength of the dome, regardless of the vessel containingthe material to be heated or boiled.

In the drawing, Figure 1 is a vertical section of a boiler andsteam-dome, and Fig. 2 represents the steam-dome adapted to heat thecontents of a wooden tank.

The vessel to is represented as hemispherical, and made of sheet metallined with a second sheet of metal, tin being preferable. A strainer isshown at Z) and a faucet at c. The steamdome e is of a-size proportionedto the capacity of the vessel a; or two might be used with one vessel.The steam is supplied by the pipe d, and the water of condensationpasses away by the pipe f. The dome is preferably of sheet-copper,tinned and united at the lower edges to the ring h that screws upon thebase a 70, through which the pipes d f pass; and this base It has aflange, i, that is connected with the bottom of the vessel at either byrivets, solder, or screws. In Fig.2 the flange t is represented asscrewed to the wood-work m, formin g part of the bottom of thecontainingvessel.

The dome a may be enlarged without increasing the size of thecoupling-rings h; or the dome may be brazed or soldered to the base 70.

It is preferable to avoid sharp angles at the junction of the dome andvessel to facilitate cleaning.

I claim as my invention- The steam-dome e and supply-pipe 61 introducedwithin the vessel or and attached at the bottom thereof, substantiallyas and for the purposes set forth.

Signed by me this 19th day of December, A. D. 1872.
